Definitions

  • the conventional semiconductor device is capable of performing a calculation as the primary function.
  • the semiconductor device it is possible to easily perform a relatively complex calculation. Further, it is possible to easily store a table with a large capacity according to various conditions. As a result, it is possible to easily achieve the temperature measurement circuit capable of suppressing an influence of a variance in the power source voltage.
  • the switches SW 1 , SW 2 , and SW 3 are provided for connecting the ADC 14 to a voltage to be a measurement subject one to one when the source voltage VG, the thermistor voltage VT, and the voltage VB of the battery Bat are measured.
  • the MPU retrieves the source voltage VG and the thermistor voltage VT thus measured as described above from the resistor 20 , the MPU is capable of calculating a temperature TB of the battery Bat through inputting the source voltage VG and the thermistor voltage VT into the following equation (1):
  • the battery monitoring IC 40 stores the divided voltage value VG′ as well as the thermistor voltage VT in the resistor 20 .
  • the source voltage VG can be obtained through the equation (3) that is modified from the equation (2):
